Ok, I've pushed the two patches ontop of EDAC's for-next branch, here:

https://git.kernel.org/pub/scm/linux/kernel/git/bp/bp.git/log/?h=edac-for-4.21-bus

and I'd appreciate testing them one more time on the big boxes you guys have.

Diffing sysfs here shows this:

which is the bus symlink:

subsystem -> ../../../../../../bus/mc0

and I think that's ok as nothing should be using it.

Thx.
